Hi,
Is there a really fast way to read a text file which contains lines of
variable length? I'm using the StreamReader to read the file, but this is
not as fast as I need it.
thanks a lot

Hi Volker,
And you are using the ReadToEnd method? http://msdn.microsoft.com/library/de...toendtopic.asp

Thanks for your reply, but I cannot use the ReadToEnd method because
I have to manipulate the read contents line per line, so I have to read
the file line per line to.

I think I found out what the problem is. When I just read the file without
manipulating the read line, it's really fast, so I have to improve these
lines.
thanks for given me this hint.

Hi, everyone,
I'm a relative novice to Python and am trying to reduce the processing time
for a very large text file that I am reading into my Python script. I'm
currently reading each line one at a time (readline()), stripping the
leading and trailing whitespace (strip()) and splitting it's delimited data
(split()). For my large input files, this text processing is taking many
hours.
If I were working in C, I'd consider using a...

I have seven huge fixed width text file that I need to import to Access.
They contain headers, subtotals, etc. that are not needed. There is also
some corrupt data that we know about and can correct once the data is in
Access (or during the import process itself). Furthermore, the text files
are poorly set up, such that some records may be "shifted" over a few
characters, and therefore the fixed width nature of the file is corrupted.

I would like to read a text file (fixed length formaated) really fast and

Using the streamreader and reading line by line, separating the line into

Hi,
I'm trying to store all of my data into one file (there're about 140 things
to keep track of). I have no problem reading a specific string from the
array file, but I wasn't sure how to replace just one item. I know I can get
the entire array, then save the whole thing (with a for loop and if
statements so that the changed data will be saved), but it seems like a lot
of unnecessary reading and writing. Is there a way to directly save...

Hi,
I need a FAST way to put the content of a file in a datatable (one record
for each line in the file).
I have a routine for it, but it takes me too much time (2-5 seconds for each
file) to put the lines in the datatable and do some actions. Does anybody
knows a faster method? The fact is: I actually only need the lines starting
with "0*" and "1*".

Hi,
I need to read specific lines of huge text files. Each time, I know
exactly which line(s) I want to read. readlines() or readline() in a
loop is just too slow. Since different lines have different size, I
cannot use seek(). So I am thinking of building an index for the file
for fast access. Can anybody give me some tips on how to do this in
Python? Thanks.

Hi,
currently I am reading a huge (about 10-100 MB) text-file line by line
using
fstreams and getline. I wonder whether there is a faster way to read a
file line by line (with std::string line). Is there some way to burst
read the whole file and later "extract" each line?
Thanks in advance,
Thomas Kowalski

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
